Abstract
Introduction
Precise anatomical knowledge of human vertebra is necessary for the safe placement of screws, pre-surgical planning and designing surgical instruments. There are no existed reports about the morphometry of vertebrae in Saudi population.
Methods
This is a descriptive study. A total of 50 spine CT was collected from the PACS system and reviewed for any abnormal pathology. Any CT with major pathology like tumor, fracture and deformity was excluded. Each vertebra was measured for the following parameters: 1- Pedicle Width. 2- Distance from Pedicle to Ant. Vertebrae. 3- Ant. Vertebrae width. 4- Canal Diameter. 5- Height of Pedicle. 6- Angle of Pedicle. All data was entered in statistical analysis program (SPSS) and compared with the existed date of other population.
Result and Conclusion: The values of the parameters with the standard deviation have been concluded and compared with the Korean, Mexican, Israeli and Indian populations which shows remarkable difference and characteristic pattern important to be addressed in safe placement of screws, pre-surgical planning and designing surgical instruments.
